Abstract
A synthetic plastic rope includes a selected number of first components having a relatively high elongation characteristic and second components whose elongation characteristic is considerably lower. In one form of the invention, the rope has a central core in which the first components are located, and a plurality of surrounding strands principally constituted of second components. In other forms, the rope does not have a core and there are a plurality of strands braided (plaited) or laid (twisted) together primarily consisting of the low elongation components, but having high elongation components distributed substantially symmetrically and which in the aggregate have substantially less mass than the low elongation components.
Claims18
A multi-component rope comprising:
- (a) a selected number of first components having first predetermined elongation characteristics, and
- (b) a selected number of second components having second predetermined elongation characteristic which are considerably lower than said first elongation characteristics, said second components having an aggregate mass which is considerably greater than the aggregate mass of said first components.
A multi-component rope comprising:
- (a) a selected number of first components having first predetermined elongation characteristics, and
- (b) a selected number of second components having second predetermined elongation characteristics which are considerably lower than said first characteristics, the maximum effective ratio of the first elongation characteristics to the second elongation characteristics being approximately 3:2, said second components having an aggregate mass which is considerably greater than the aggregate mass of said first components.
A multi-component rope comprising:
- (a) an even number of strands greater than two, said strands being plaited in pairs, said strands having first components with first predetermined elongation characteristics distributed substantially symmetrically in selected ones of said strands, said selected strands being disposed substantially opposite one another, and
- (b) selected number of second components having a second predetermined elongation characteristics which are considerably lower than said first elongation characteristics, said second components having an aggregate mass which is considerably greater than the aggregate mass of said first components.
A multi-component rope comprising:
- (a) an even number of strands greater than two which are plaited in pairs,
- (b) a selected number of first components having first predetermined elongation characteristic, said first components being distributed substantially symmetrically in selected ones of said strands which are disposed substantially opposite one another, and
- (c) a selected number of second components having second predetermined elongation characteristics which are considerably lower than said first characteristics, a maximum effective ratio of the first elongation characteristics to the second elongation characteristic being approximately 3:2.
